This invention relates generally to the mattress making industry, andparticularly to a machine for inserting eyelets in mattress borders.

The main object of this invention is the provision of an efilcient formof eyeleting machine by means of which a plurality of rows of eyeletsmay be inserted through several layers of materials for the purpose ofuniting same, and at the same time providing ventilation for themattress.

The second object is to provide an improved form of eyelet feedingdevice which will insure a constant and uniform flow of eyelets to theinserting mechanism.

These, and other objects, will become more apparent from thespecification following as illustrated in the accompanying drawings, inwhich:

Referring in detail to the drawings, .there is '5 shown a table 26 whichis held at a convenient height by means of the legs 2|. Mounted on thetable 20 is a housing 22 upon which is secured the operating motor 23.The motor 23, through the belt 24, drives the pulley 25 which, 10through the pinion 23, drives the idler gear 21 to which is attached thepinion 28 which, in turn, drives the cam drive gear 29 which is keyed tothe cam shaft 30.

Mounted on the cam shaft 30 is a punch cam 15 3! and a needle cam 32, aswell as a hopper shaking cam 33. The housing 22 is provided with alateral extension 34 which terminates in a head 35 in which is mountedthe punch slide 36 from whose lower end project the tubular punches 2037, three of which are illustrated, but holes are provided for twopunches equi-distant from the center line of'the slide to adapt thedevice for inserting a double row of eyelets instead of a triple row, asis shown throughout the drawings. 25

Slidably mounted in the slide 36 is the needle holder 38 which isprovided with a horizontal recess 39. Needles 40 are held in the holder38 by means of the set screws 4|. The holder 38 is also drilled for usewith two needles, as suggested, 30 for the punches.

In the lower portion of the slide 36 is formed a slot 42. The slide 36is held in position by means of a cover plate 43.

On the back of the head 35 is formed a clove 35 tailed guide 44 on whichis mounted-the vertical movable housing 45 in which journals the upperfeed roll 46. In the top of the housing 45 is threaded a hollow bushing4! in which is mounted a spring loaded plunger 48 which is at- 40 tachedby means of a link 49 to the crank arm 50 on the shaft 5| which journalsin the bearing 52 disposed on top of the head 35. A weighted arm 53 onthe shaft 4| urges the plunger 48 downwardly. A stop 54 limits thedownward 45 movement of the roll 46. The roll 46 is preferably providedwith grooves 55 which are in alignment with the eyelets 5B which areinserted in the border strip 51 which passes over the table 20 from theextension table 58.

A lower feed roll 59, preferably fluted, is mounted on the shaft 60which journals in the bearings 6! on the under side of the table 20. Theshaft 60 has secured thereon a ratchet wheel 5.2 which is prevented fromturning in a back- 55 ward direction by means of the holding pawl 63 andis driven in a feed direction by means of the pawl 64 on the rocker arm85 which pivots on the shaft 60.

A rocking motion is imparted to the arm 65 by means of a link 66 whoseupper end is connected to the crank disk 61 by means of the stud 68. Thedisk 61 is keyed to the shaft 30' and is provided with a pair of holes69 of unequal distance from the center of rotation of the disk 61, thepurpose of which is to provide a variation in the length of the feedingstroke for the border strip 51.

Owing to the fact that the ratchet wheel 62 and the crank 61 rotate indifferent planes it is desirable to provide universal connections at theupper and lower ends of the links 66.

The roll 59 is directly below the roll 46 :and its top side extendsthrough a slot 10 in the table 2.0.

Directly below the punches 31 and in alignment therewith are the dies 1Iwhose upper surface 12 is shaped to spread the lower'end 13 of theeyelet56 when the eyelet is forcibly moved downwardly upon the die H by meansof the punch 31.

Pivotally mounted in the extension 34 is a needle cam arm 14 whoseroller 15 is urged against the cam 32 by means of the spring 16. The end11 of the needle cam arm 14 is provided with a bolt 18 having a T head19 which is horizontally slidable within the recess 39.

Also pivotally mounted in the extension 34 is the punch cam arm whoseroller 8| is urged toward the cam 3| by means of the spring 82. The arm80 is provided with a bolt 80-A which is slidable in the slot 42. Theshape of the cams 3| and 32 is such that their rotation will first causethe needles 40 to pass through the eyelets 56 and perforate the toplayer of the border strip 51 (as shown in Fig. 17) after which thepunches 31 are caused to descend and force the eyelets 56 through thetop layer of fabric (as shown in Fig. 18). The needles 40 are held atrest while the punches 31 continue to descend and complete the operation(as shown in Fig. 19).

Referring now to the eyelet feeding section of the device, same will beseen to consists of a hopper 83 having an extension 84 on the rear sidethereof by means of which it is pivotally attached to a tubular sleeve85 into which extends the upright pin 86 which is fastened to the hub8'! of the lever 88. The, sleeve 85 has a downwardly extending arm 89which is attached to a spring loaded rod 90 which, in turn, is hingedlyconnected to a clamp 9| on the bent rod 92 whose lower end is pivotallyattached to the arm 93 which is supported by the tubular extension 94 ofthe hopper 83.

The lever 88 has connected to its lower end a link 95 which, in turn, isconnected to the lever 96 on the rock shaft 91 which journals in thehousing 22. The inner end of the shaft'91 has secured thereon a hoppershaking cam lever 98. The lever 98 carries a roller 99 which is urgedtoward the cam 33 by means of a spring I00. The cam 33 is constructedsubstantially as shown in Fig. 9 for the purpose of providing a seriesof shaking movements for the hopper 83, and to hold it still during theeyeleting operation by means of the dwell I0I.

The hopper 83 is provided with a false bottom I02 which is urgedupwardly by the spring I03 which surrounds the guide rod I04. Thepurpose of the false bottom I02 is to hold the eyelets 55 7 near theoutlet opening I05. Obviously, the more eyelets contained within thehopper 83 the lower will be the floor I02, due to the increased weight,and the tension of the spring I03 should be such that the uppermostlevel of the eyelets 56 is substantially the same as the bottom of theoutlet 5 I05.

Communicating with the outlet I05 and attached to the hopper 83 is amultiple channeled chute I06 whose lowermost end I01 can occupy aposition underneath the punches 31. In order 10 to prevent the eyelets56 from becoming lodged in the channels I08 there is provided above eachchannel a rattler shoe I09 for-each channel I08. The shoes I09 aremounted on the horizontal top portion IIO of the bent rod 92. The upperside 15 I I I of each shoe I09 is curved to permit its inner end II2 toenter the opening I05.

The shoe I09 is provided with a shoulder II3 the purpose of which is tomove the eyelets back into the hopper unless their smaller ends have 20passed downwardly into the channel I08. The shaft H4 is supported by thestandard H5 and carries the hub 81.

Across the lower end I01 of the raceway is secured the horizontal bar II6 which rests upon 26 the horizontal holding bar II1 which is pivotedto the head 35 by means of a pin I I8. The forward end II9 of theholding bar H1 is curved upwardly and its opposite end I20 is urgeddownwardly by a compression spring I 2I which re- 30 acts against thelug I22 on the head 35.

'Slidably mounted in the head 35 is a horizontal latch I23 whosedownturned end I24 is normally in front of the bar II6. A spring I25,which is mounted on the head 35, urges the latch end I24 38 toward thebar I I6 and moves the bar I I6 against the stop I26.

Hinged to the cover plate 43 on the pin I21 is a finger I28 whichnormally engages the rear side I29 of the bar H6. The finger I28 has on40 its rear side an inclined face I30 above which is secured a plate I3Ito the slide 36. The lower end I32 of the plate I3I engages the race I30of the finger I28 when the slide 36 moves downwardly causing the lowerend of the finger I28 to 45 move the chute end I01 out of the way of thedescending punches 31 against the action of the spring I25. The fingerI28 is urged away from the bar I I6 by the light spring I33.

It will be observed in Fig. 11 that pointed walls 50 I34 occupy thesides between the shoulders H3 and that they extend to the wall I35which forms a stop for the rattler shoes I09. The outlet of each channelor raceway I08 converges slightly, and one side I36 is supported by aspring I31. 55

It is desirable to provide the table 20 with a spring stripper plate I38whichiacilitates the passing of the fabric'over the dies 12, and alsoinsures the removal of the riveted eyelets 56 from the dies at thecompletion of each operation. 5

The operation of the machine is as follows: Assuming that there is asupply of eyelets 56 in the hopper 83 and that a piece of bordermaterial 51, composed of two ply fabric with an intermediate filler, isfed from the table 58 between the 65 rolls 46 and 59 and that the motor23 is operating, it will be seen that the rotation of the cam 32 willfirst move the needle holder 38 downwardly through a waiting eyelet 56.While this is taking place the punch operating cam 3I moves the 70 slide36 downwardly forcing the eyelets 56 toward the point of the needles 40,which have stopped just above the highest point of the dies H. Thepunches 31 continue their movement after the chute end I01 has beenmoved out of the way by the plate I3I, the descending movement of thepunches 31 continuing until the eyelet 56 is reformed (as shown in Fig.19) to constitute a tuft between the two plies of fabric in the border51.

The cams 3I and 32 then restore the needles 40 and the punches 31 totheir uppermost position-that is, clear of the border 51and the crankdisk 61, through its connections 66, and 64 then actuates the feed roll59 moving the border 51 longitudinally to a new position ready for theinsertion of three more eyelets 56.

In order that the channels I08 may be kept filled at all times a shakingmotion is imparted to the hopper 83 by the cam 33, and in additionthereto the shoes I00 are given a rattling motion through the rod 92 forthe purpose of preventing the eyelets 56 from becoming caught on piecesof lint, or otherwise lodging in the channels I08. If, for any reason,the eyelets should become lodged so that the shoes I09 could notoperate, the yielding action of the spring-urged plunger would preventthe destruction of the parts.

If it is desired to vary the longitudinal spacing of the eyelets 56 withrelation to the border 51 this is accomplished by shifting the positionof the stud 68 with relation to the axis of the shaft 30.

As previously stated, if it is desired to use two rows of eyeletsinstead of three (as shown) then the needles 40 and the punches 31 areshifted in their respective holders, one set being removed entirely andthe machine operated as before. In this event it is necessary to shortenthe link 95 by utilizing the extra hole I39 which will shift theposition of the chute end I01. Obviously, if no needle enters theeyelets in the unused channel I08 no eyelets will be drawn therefrom.

It is desirable to provide retaining wires I40 over the inclined portionof the channels I08 to prevent the escape of the eyelets 56 therefrom.The wires I40 are supported by the cross wires MI.

I am aware that numerous forms of eyeleting machines have beenconstructed in the past in which a plurality of eyelets may be passedthrough several sheets of fabric for the purpose of securing sametogether. The patent of Coles No. 417,988 is an example of this type ofmachine. It is therefore not my intention to cover such devices broadlyand I have restricted my claims to the specific features of my devicewhich render same more positive in its operation under unfavorableconditions, and requiring less skillful attention in order to maintainthe machines in an operative condition.
